Squanto804,
I love my Powerdyne and as you can tell by my numbers they make good power. I may get flamed, but I would personally get another supercharger. I just do not trust the belt driven(Powerdyne) to be that reliable as gear driven ones (Vortech, Paxton, and I think Procharger). Some of the latter has came out with their own versions that are self lubricating and quieter. I have been thinking about the Paxton Novi 2000, they are suppose to be good up to 24-27 lbs of boost. Even though you can not get near that on a stock engine without self destructing of course. But the Powerdyne is good for the amount of money invested. Just my 2 cents.

Kevin,
I tried what you suggested last night on my trip to town and again on the way to work this morning. I am maxing the boost gauge at a whopping "0" psi at around 2500-3000; anything above that makes it go more and more negative (vacuum). I could only stand to rap it out to around 4500, at which point I couldn't stand to hear it struggle any more (it seemed to just flatten out). But at that 4500, I was at probably back to an idle vacuum. Very weird!!! Where did the boost go? I haven't had a chance to call Powerdyne back today, but this is definitely not right. I probably will still return the whole thing to them eventually, but I may make them first swap out my blower unit just to see if that's it. The belt must be broken inside??? I'll keep you posted.
